The Seventies 2-39-47-13-12-50, seen from the bench

The Glashütte Original Seventies 2-39-47-13-12-50 is a contemporary reinterpretation of 1970s aesthetic through Saxon watchmaking tradition. The 40mm stainless steel case features squared geometry with a Big Date window and threadbare hands, paired with the automatic caliber Glashütte Original 39-47. The strap width is 26mm, a distinctive choice that corresponds to the case lugs and distinguishes this model from standard contemporary sports watches.

Frequently asked questions

What is the lug width of the Glashütte Original Seventies 2-39-47-13-12-50?

The lug width of the Glashütte Original Seventies 2-39-47-13-12-50 is 26mm. This dimension, measured from lug shoulder to lug shoulder, is a distinctive characteristic of this model. It is essential to verify this measurement before purchasing a strap, as an incorrect size compromises both aesthetics and secure wear.

Which strap is recommended for the Glashütte Original Seventies 2-39-47-13-12-50?

For the Seventies 2-39-47-13-12-50, we recommend: alligator straps in dark tones for formal occasions; calf leather straps with vegetable tanning for daily wear with natural patina development; nylon NATO straps for durability; FKM rubber straps for versatile sportive use. The choice depends on context and personal aesthetic preferences.

How do I change the strap on a Glashütte Original Seventies?

To change the strap, use a spring bar tool or dedicated instrument to push the spring bar pin inward, releasing the lug from the case hole. Repeat on the opposite side. Align the new strap's holes with the spring bar pins and push until you hear a click. We recommend executing this operation carefully to avoid scratching the stainless steel case.

Is an aftermarket strap compatible with the Glashütte Original Seventies 2-39-47-13-12-50?

Yes, any quality strap with a 26mm lug width is compatible with the 2-39-47-13-12-50. Aftermarket straps allow for personalisation: it is important to select premium materials (alligator, vegetable-tanned calf) and reliable suppliers to ensure durability and aesthetic coherence with Glashütte Original's manufacturing rigour.

How long does a leather strap last on a Glashütte Original Seventies?

A high-quality leather strap (alligator or vegetable-tanned calf) typically lasts 4-6 years of regular use. Longevity depends on UV exposure, humidity, wearing frequency, and maintenance. Leather subjected to vegetable tanning develops a natural patina over time, improving aesthetics and character. We recommend periodic maintenance and rotation with other straps to extend useful life.
